LOS ANGELES - August 11, 2003 - Teledyne Technologies Incorporated (NYSE:TDY) today announced that Teledyne Energy Systems, Inc., was awarded a $4.3 million contract option to develop and deliver an "engineering model" Proton Exchange Membrane (PEM) fuel cell power system rated at 7 kilowatts to NASA's Glenn Research Center. The 20 month option represents Phase II of Teledyne Energy Systems' contract awarded in 2001 to develop a more reliable, powerful and low maintenance fuel cell power system for use in NASA's Second Generation Reusable Launch Vehicle (RLV) Program. In addition, the contract includes a second, optional $1.2 million advanced technology task.

The engineering model will include the PEM fuel cell power module and all related ancillary components packaged into a single power plant assembly. The power plant assembly is designed to conform to operational parameters necessary for use in Next Generation Launch Technology vehicles, the Orbital Space Plane and the Space Shuttle. The engineering model will demonstrate key technology requirements, including the ability to meet the power profile, to operate in a space environment through testing in a thermal vacuum chamber, to operate under launch and flight conditions through testing on a vibration table, and to provide drinking water for the flight crew.

"This award continues a period of contract wins by Teledyne Energy Systems in the space power sector and demonstrates our commitment to quality, reliability and innovation," said Robert Mehrabian, chairman, president and chief executive officer of Teledyne Technologies. "The award allows Teledyne Energy Systems to expand its experience in unmanned space power systems into manned space missions where our history of reliability and safety are even more important."

The Phase II project follows the success of the $1 million, 17 month Phase I, in which Teledyne delivered a 5 kilowatt breadboard model to NASA in early 2003. The 5 kilowatt unit is undergoing testing by NASA to evaluate its ability to respond to power profiles typical of a manned space mission. Advances over the 5 kilowatt unit planned for Phase II include the use of an upgraded fuel cell stack, improved packaging and inclusion of an active water management system rated for microgravity use.

PEM fuel cells convert the energy available in hydrogen and oxygen to electricity and water. Under development by Teledyne for a wide array of commercial applications, PEM fuel cells offer several advantages over the alkaline fuel cells currently used for spaceflight, such as the potential for lower cost due to their wider commercial uses; lower maintenance costs due to their simpler design, which is based on solid-state technology; and a greater operational flexibility created by their wide power band.
